Estudo da implementação de métodos de conversão térmica tradicionais no potencial energético da borra residual da indústria do petróleo uma revisão

Abstract

Oil sludge (OS) is a complex mixture of hydrocarbons, organic impurities and water, which is one of the major problems encountered in the industry due to its logistical difficulties (storage, transport and destination), causing economic and environmental damage. On the other hand, as it contains complex ramifications of heavy hydrocarbons in its structure, this residue can be recycled and converted into smaller molecules, through processes such as thermal or catalytic cracking. The objective of this work was to develop a bibliographic review on the residual oily sludge from the oil industry and study its energy potential through traditional thermal methods of the industry: pyrolysis and gasification. For this, information was sought in databases such as Periódicos Capes (PC), Scifinder, Web of Science (WoS) and Scopus. As a result, four case studies were gathered whose treatment techniques were compared in terms of their converted products and their energy potential. Thus, it was noted that the choice of the optimal method is linked to three parameters: a) Purpose of the treatment; b) Type of sludge to be treated and c) the processing potential of the plant. With the execution of this review, it is expected that the study carried out will contribute to thermodynamic knowledge and process optimization, providing information on the production of nobler products.
